Might be a software glitch, there were multiple threads back in the W213 forum but that was a year or so ago with this same issue of everything suddenly shutting down.

Just in case, did you try pressing the power button (where the volume knob) is?

Disappointing to hear it didn't work, I forgot but there was a way to force reboot the system, I think it was pressing a combination of buttons. I guess your next step is to bring it to a workshop if it doesn't work, I mean your service is also due, no?

Dang, I am sorry to hear that man.

Hmmm, something that you could try: I don't know if this is a good idea (disconnect the 12V battery) but I am worried that it removes more than you want (like the steering angle data on some MBs and you need calibrate it again) plus the windows might or might not need to reset as well (as in they are not going up or down fully). Plus since you have a 48V mild hybrid system, I am not sure if that system will just keep most of the vehicle powered anyways.

Anything show up as codes when you plug in your scanner?
